roadmap(agent phase 1): maintainer auto-maintain (cloud action layer)

[JSONbored]

Parent: #772 · Milestone: M3 (2026-06-27)

Goal

Cloud action layer on the gate/review engine — acts on GitHub state (request-changes/approve/merge/close/label), never source.

Children

• feat(agent): maintainer write-actions layer (request-changes/approve/merge/close/label) #778 maintainer write-actions layer
• feat(agent): approval-queue UX + notification channel #779 approval-queue UX + notification channel

Prerequisites (Wave 1 / M1)

#551 merge-readiness · #538 appeal/override · #555 manifest-as-gate · #552 first-timer gating · #540 reviewer routing · #554 telemetry · write-safety B1/B2/B3/B6.

Done when

Repo can auto-request-changes/approve/merge-clean/close-noise behind a per-repo autonomy dial with audit feed + override. Dry-run before each goes live.
